how do I get my site listed in the yahoo directory?

You need to pay money.

Recurring annual fee of US$299 to maintain the listing in the Directory for the subsequent year.

For sites that include adult content or services, the nonrefundable initial fee is US$600 and the recurring annual fee is US$600

But personally, I don't think paying £199 is worth a directory submission.
If you create a couple of great articles and a few press releases or a video and promote that, it would make more sense. (my two bits.. )
